Why Do Membranes Get to Choose What PASSES Through? - starpoint

Stay Informed

Yes, membranes can be designed to remove a wide range of contaminants from water, including dissolved solids, bacteria, and viruses. This technology is commonly used in reverse osmosis and nanofiltration systems.

How are membranes made?

When a substance interacts with a membrane, it undergoes a process called transport. There are three primary modes of transport: diffusion, osmosis, and active transport. Diffusion occurs when molecules move from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane. Active transport, on the other hand, involves the movement of molecules against their concentration gradient, often requiring energy.
